When sickle cell patients arrive at emergency rooms, they often have difficulty getting proper treatment. Paula Tanabe, an associate professor at the Duke University School of Nursing, is working to change that.

Sickle cell disease, a genetic blood disorder most common among people of African descent, affects 100,000 Americans. It causes normally disk-shaped red blood cells to take the form of pointed crescents or sickles.

Common complications include strokes, anemia, severe infections and damage to blood vessels and internal organs. Many people with the disorder are unable to work and and lack health insurance.

Acute and unpredictable pain, severe enough to require large doses of narcotics, is a well-documented feature of sickle cell disease. But Tanabe has found that patients in sickle cell crisis often aren't treated properly by doctors and nurses. They erroneously think the patients may be running scams, seeking drugs.

Patients suffering recurrent episodes know what works for their pain, but some doctors and nurses take that knowledge a sign of addiction. Patients with sickle cell pain wait an average of 30 minutes longer for pain medication than people with other extremely painful conditions, such as kidney stones, Tanabe's research shows.

Tanabe says better training of health providers and changes in emergency room procedures can improve the care that sickle cell patients receive. She spoke recently with our partner Kaiser Health News. The following is an edited transcript of the interview.

Paula Tanabe: What brings people to the emergency room is a crisis in which the blood can't deliver oxygen to the extremities. It is a sudden onset of severe, excruciating pain, which people describe as feeling as if all their bones are breaking. Others describe it as an hourglass and their blood is "stuck." The pain is so bad and sudden that people require high doses of opioids.

Patients who have a regular health care provider and have chronic pain are usually prescribed oral opioids to have at home. They take pain pills by mouth. [But] at the time of a really bad crisis, the pills don't work any more. People need to come in for intravenous pain medication. They usually try to avoid coming into the ER at all costs because they just have to wait a long time.

Are people with sickle cell likely to be addicted to painkillers?

There are no data to support that sickle cell patients have any more likelihood of being addicted than anybody else.

You compared the treatment in emergency rooms of patients with kidney stone pain and with sickle cell disease. What did you find?

A lot of white people get kidney stones and that pain is really, really horrible. Even though sickle cell patients had higher pain scores and were triaged appropriately higher, they still waited longer.

Racism and the disease stigma itself are two barriers that you just can't get away from. Clearly we can't pretend that racism doesn't play some part in this. If this were a white disease, people still wouldn't be dying in their 40s. That's the bottom line. Sickle cell was discovered 102 years ago and there is only one drug, hydroxyurea, and blood transfusions to treat it.

So you believe racism has discouraged progress in treating sickle cell?

It is a rare disease. However, there are other rare genetic diseases that get a lot more attention and people are not afraid to talk about. Cystic fibrosis is a good example, and way more rare than sickle cell. It's a white disease. There is some attention to sickle cell, but it needs more dollars and more research. There are very few hematologists, very few providers across the country, who specialize in it. Patients do need a good hematologist or sickle cell expert to take care of their disease.

There has been progress. People didn't used to live to be adults. Kids would die of stroke or of really bad infections before they were 20, and in some countries they still do. The fact that we have adults is a good thing. All kids are screened at birth in the United States. Once you identify a child, they go on penicillin until they're five, and then they don't get the really bad infections and die from that.

You have done research that documents the problem. Your current research examines methods of improving treatment. What does that involve?

We are implementing some education and some analgesic protocols. We hope this will help lower the time needed for patients to get analgesia, or pain control, and admission rates. We've administered a baseline attitude survey to providers. We will administer it again. We'd like to see improvement in clinician attitude. We're really looking at patient satisfaction, provider attitudes, and then a lot of efficiency outcomes. Another aim of our grant is to put a toolbox together of all the protocols and the educational materials that we've developed and make it available.
